On August 6, 2026, Radian Group’s board of directors adopted the Radian Group Inc. 2026 Inducement Grant Equity Plan, as amended as of August 6, 2026 (the “Inducement Plan”), which amends the Radian Group Inc. 2026 Inducement Grant Equity Plan to increase the maximum aggregate number of shares authorized for issuance under the Inducement Plan from 500,000 to 674,220. Under the Inducement Plan, the Company may grant equity-based awards to newly hired employees as a material inducement to employment in accordance with New York Stock Exchange Listed Company Manual Section 303A.08. As previously disclosed in the Company’s press release issued on June 3, 2026, effective on his employment date of June 1, 2026, the Company granted Michael Weinbach 150,000 time-based restricted stock units and 262,110 performance-based stock units under the Inducement Plan. The performance-based awards are subject to performance-based vesting conditions such that they may vest between 0% and 200% of the grant date number (up to a maximum of 524,220 shares). The additional 174,220 shares available under the amended Inducement Plan were added solely in the event that the previously-granted performance-based awards to Mr. Weinbach vest at the maximum level, and do not represent new awards under the Inducement Plan. As a result of the awards granted to Mr. Weinbach on June 1, 2026, no additional shares remain available for issuance of awards under the Inducement Plan.

The foregoing description of the Inducement Plan is qualified in its entirety by reference to the full text of the Inducement Plan, a copy of which is filed as Exhibit 10.11 and is incorporated by reference in this report.
